hey.Actually got this problem with my tank which houses only one green terror.Even after a few hours after the tank is cleaned it starts emmiting a foul odour which many hobbyist are familiar with.Any remedies for this odour.The terror is fed dry worms and instinct spirulina food.Can they be the cause?????????????????????/

This sounds like a ammonia problem. This is specially amplified by the fact that you dont have afiltration system.

Could you let us know how big is the tank and whats the frequency of water changes. Its the lack of denitrifing bacteria that could be causing a ammonia build up, also let us know whats your water source and where are you put up.
Would recomend you put a filter in your tank, and areate the water.

Tank Cycle should have taken care most of problems, Filter might also be a source of problem. Water changes and its frequency could also be another issue. Over feeding and non removal of residue is also another source of ammonia buils up.

To De-oderise the system in a non planted tank, I would use Activated Carbon if the problem persists. Also this would remove toxic's out of water.

No Filter in any aquarium is a strict no-n
That too for a chichlid who has good diet. Even in discus tanks where people do daily water changes there are sponge filters.
The importance of filter cannot be over emphasised.
Get a filter, establish nitrogen cycle and your problems will go away on their own.

You have to give more details if you want useful advice. What is the tank volume, what sort of filtration, do you have a substrate; planted or not; what schedule of water changes do you follow; do you monitor water parameters, do you vaccum the substrate to remove debris, was the tank properly cycled before adding fish, could overfeeding be occuring.... ?

Without this information any answer would be incomplete.

the tank is 1 1/2 ft.It has no substrate.I change water every week and sumtimes every 4 days.The tank was cycled properly.no case of overfeeding since the lone green terror does not leave nething to decay.I mean everything is eaten within 10-15 minutes.

Ok. Are you changing very large amounts of water each time ? This can effect your biofilteration.You dont have a filter or substrate so whatever few nitrobacter are present are probably being depleted every time you do a large change. You mentioned in your first post that you "clean" the tank. Can you specify what you mean by that ? Because if you are actually scrubbing it then you are in a new cycle every time.
I suggest you get some established filter media from your LFS or a friend with a mature tank, get a good filter and start again.

thnx for all the opinions guys,the mistake i repeatedly commited was to use soap to wipe the glass clean.Ive since stopped doing it and no more smelly tank,perhaps the soap was killing the useful bacteria.Thnx again

Well
It is good that the soap has not killed your gt and yes it definitely needs a filter.
Without a filter you will never have good bacteria colony in a bb tank
